I really enjoy teaching. On occasion, I'll give private instruction. I have a couple of friends who asked me to come to their home, evaluate their cutlery situation, and teach them how to sharpen. What I found was about what I expected, a lot of cheap knives and a couple decent ones. I was somewhat surprised to find that they had a King stone, which I used to teach them how to sharpen their knives. By the time I left, they had a decent feel for how to use the stone and the very dull knives were quite useable. I gave them some advice on how to fill out their lineup of stones and knives as they start on their wedding registry. It was really enjoyable watching them suddenly start to "get it" especially as they used the stone.
